Description

[Detailed description of the invention] The present invention relates to a latch mechanism in a cabinet.The purpose of this invention is to eliminate the pull on the front plate of the drawer to organize the front of the cabinet in an orderly manner, and to improve the drawer operation of the drawer. This makes it easier. Therefore, in the present invention, a gap is provided between the front plates of the vertically layered drawer for inserting a finger, and an inverted ladder is provided opposite to the proximal oblique edge of the latch plate, which is provided symmetrically and has elasticity in the locking direction. The present invention proposes a latch mechanism for a cabinet, which is characterized by providing a shaped actuator and interlocking the actuator with a knob facing the gap. The gist of the present invention will now be explained in detail.

Fig. 1 is a perspective view showing an example of a cabinet equipped with the latch mechanism of the present invention, Fig. 2 is a perspective view of a back plate housing the latch mechanism, Fig. 3 is an exploded perspective view of the main parts of the latch mechanism, 4 is a partially cutaway cross-sectional plan view of the same latch mechanism, FIG. 5 is a rear view of FIG. 4, and FIG. 6 is a central vertical cross-sectional side view of FIG. 4. In the drawing, reference numeral 1 denotes a cabinet, which has a plurality of drawers stacked vertically, with gaps d provided between the front plates 2, 2, and 2, and at the center of the upper edges of these front plates 2, 2, and 2. A knob 3 made of synthetic resin or the like is shown. A back plate 4 shown in the second figure is fixed to the back side of these front plates 2, 2, 2, and a latch mechanism shown in the third figure is housed.The main parts of the latch mechanism are as follows.
The aforementioned knob 3, connecting plate 5, actuator 6, and latch plate 7
As shown in the figure, the actuator 6 has an inverted ladder-shaped inclined side surface 6a, and the inclined side surface 6a is connected to a latch plate 7.
The proximal end bevel 7a is opposed to the proximal end bevel 7a. The proximal end of the latch plate 7 is bent into a U-shape so that the actuator 6
A bent portion 7b is formed which goes around half of the side of the cabinet 1, while a latch portion 7c is provided at the tip, and a stopper 8 of the side plate 1a of the cabinet 1 is formed as shown in the fourth figure.
The latch plate 7 is pressed in the locking direction via a pressure expansion spring 9. Furthermore, latch plate 7
is the guide frame 1 shown in FIGS. 2, 4, and 5.
0, and its latch portion 7a is made to protrude from the side through-hole 4a of the back plate 4. Further, the actuator 6 has its upper part accommodated within the guide frame 11, and the through hole 4b of the back plate 4 and the guide frame 1.
It is connected and fixed to a knob 3 through a connecting plate 5 passing through a through hole 11a of the knob 1, and the knob 3 has its top surface 3a the same as the top edge 2a of the front plate 2, as shown in the sixth figure. It is arranged to be located on a flat surface.

To explain the mode of operation of the latch mechanism of the present invention having the above configuration, as is clear from Fig. 4,
The pair of symmetrically arranged latch plates 7, 7 constantly press the latch portion 7c toward the sides of the drawer by means of the expansion spring 9, so that the drawer cannot be moved into the cabinet 1.
By pushing the latch portion 7c inward, the latch portion 7c passes over the stopper 8 and enters the inside, causing the tips of the hook portions to face each other and performing a locking action. In this state, the knob 3 is , latch plate 7
The actuator 6 is pushed up by the proximal beveled edge 7a of the actuator 6, and is pushed up via the connecting plate 5, so that the top surface 3a is supported on the same plane as the top edge 2a of the front plate 2, as shown in FIG. That's true. Therefore, as shown in the first figure, a regular gap d is always maintained between the front plates 2, 2, 2.

Next, to pull out the drawer, insert your finger downward into the gap d in the upper center of the front plate 2, push down the knob 3, and then pull the front plate 2 toward you, and the pair of latch plates 7 will be activated. Due to the descent of the child 6, its inclined side 6
As a result of pressing the latch plate 7 in the latch release direction by pressing the latch plate 7 against the proximal bevel 7a of the latch plate 7, the latch portion 7c is retracted from the position facing the stopper 8, and the drawer can be easily pulled out. . In addition, pickle 3
Regarding the connection relationship between the connecting plate 5 and the actuator 6, the knob 3 and the connecting plate 5 or the connecting plate 5 and the actuating element 6 can be integrally connected.

As described above, according to the present invention, by providing a certain gap d between the front panels of the drawer without providing a handle, the front surface of the cabinet can be constructed in an orderly manner, and the aesthetic appearance can be further improved. Furthermore, since the finger is inserted downward from the top of the front plate, the drawer operation can be performed more easily, while the latching action is performed on the left and right sides of the drawer, so the locking action is reliable, and the above-mentioned Along with the improvement in aesthetic appearance, the practical benefits are considerable. Furthermore, the knob 3 of the latch mechanism of the present invention mentioned above was made to peek out from the center of the upper edge of the front plate, but conversely, by making the knob 3 peek out from the center of the lower edge of the front plate, the finger can be oriented upward. It is also possible to operate the latch mechanism by inserting it into the gap d.
